One mole of any gas at 298 k and 1 atm occupies a volume of 22.4 l. true or false

- False.

Explanations:- One mole of any gas at STP occupies 1 volume of 22.4 L.

STP means standard temperature and pressure. Standard temperature is 273 K and standard pressure is 1 atm.

Here, in the statement the given temperature is 298 K which is not the standard temperature and so the volume of 1 mole of the gas will not be 22.4 L.

The volume could be calculated using ideal gas equation:

PV = nRT

R is the universal gas constant and it's value is .

let's plug in the values and calculate the volume for 1 mole of the gas:

V = 24.5 L

The volume for 1 mol of the gas at 298 K and 1 atm is 24.5 L and hence the statement is false.
